What Is Cholestasis of Pregnancy?
Suffering from itchy hands and feet? It could be a symptom of cholestasis, a rare but serious liver condition that can result in stillbirth.
It's normal to experience mild itching during pregnancy as your bump grows and your skin expands and stretches—in fact, almost a quarter of all pregnant women complain of itchy skin. However, more intense, persistent itchiness could be a symptom of intrahepatic cholestasis of pregnancy (ICP), a group of liver disorders specific to pregnancy that interfere with the flow of bile.
Though there's no long-term risk to your health, this condition can be dangerous to your baby if it goes untreated. That's why you should always tell your doctor if you have significant itching.
What is intrahepatic cholestasis of pregnancy (ICP)?
ICP impairs the functioning of the liver, resulting in a buildup of bile—a fluid produced in the liver to digest fats—in the blood. Itching is triggered when the blood deposits these bile acids into the tissues, which can be uncomfortable but not life-threatening. For your baby, however, elevated bile levels are toxic and can cause complications if left untreated, including preterm birth, fetal distress, meconium in the amniotic fluid, and stillbirth.
What are cholestasis symptoms?
Here's how to tell the difference between the harmless itching many women experience during pregnancy and ICP: "Itching associated with cholestasis occurs in the second and third trimesters of pregnancy, and it's typically severe, particularly at night," explains Christine Miller, M.D., a professor of reproductive medicine at the University of California School of Medicine. "It can be all over the body but is often worse on the palms and soles."
Tell your doctor promptly if you experience severe itching to rule out the possibility of ICP. He or she will likely order blood tests and bile acid tests, and evaluate your liver function to determine a diagnosis. "If you are experiencing severe itching and your doctor is unfamiliar with ICP and resistant to learning more about the condition, get a second opinion," says Dr. Miller.
In the majority of cases, itching is the only symptom reported. However, less common symptoms associated with ICP may include:
Dark urine and/or pale stool
Respiratory distress syndrome (RDS) and failure to establish breathing
Yellowing of the skin and whites of the eyes (aka jaundice)
Loss of appetite
Symptoms of ICP usually resolve after delivery, but there is a high chance of recurrence with subsequent pregnancies.
Treatment for cholestasis of pregnancy
The good news for you and your baby is that ICP is treatable. In fact, with active management the risk of stillbirth is less than 1 percent, which is the same as an uncomplicated pregnancy. According to Dr. Miller, the most common active management tactics typically include:
Taking the prescription medication Ursodiol. This medication helps decrease bile acid levels in the mother's bloodstream and relieves itchiness. Moreover, it may help protect the baby in several ways including preventing premature aging of the placenta, reducing the risk of meconium staining, protecting the baby's heart and cells against damage due to bile acids and restoring the placenta's ability to transport bile acids away from the baby.
Early delivery at 36 or 37 weeks, or at the time of diagnosis if later.
Additional screenings to monitor your well being and your baby's. These tests may include blood work to monitor your bile acid levels; nonstress tests, which can detect signs of fetal distress; and biophysical profile scores to measure the volume of amniotic fluid and fetal activity.

Treatment for general itchiness during pregnancy
It's important to note that itchy skin during pregnancy can be very normal. "Many women get itchy for no other reason than the skin over the belly is continually being stretched and this can lead to dryness, stretch marks, and itching," says Dr. Hakakha explains. "Most cases are harmless."
To cut down on itching, here are a few tips from Michele M. Hakakha, M.D., a board-certified OB/GYN and co-author of Expecting 411: The Insider's Guide to Pregnancy and Childbirth:
Use a moisturizer twice a day and immediately after a shower or bath.
Use anti-itch creams like calamine lotion, 1% hydrocortisone cream, or diphenhydramine (Benadryl) cream.
Avoid taking really hot showers which can dry out your skin.
Drink plenty of water to stay well-hydrated.
Try an oatmeal bath.
Avoid spending long periods of time in hot weather or in the sun (which can make itching worse).
